Over the years, public relations firms and political consultants have become more daring in their methods and shrewder with their strategies; selling their candidate's policies and platforms to the Great Unwashed Masses with such flippant ease you'd think they were marketing a new flavor of tartar-control mouthwash. (Wow, this tax cut is winter-minty fresh and it keeps poor people perpetually disenfranchised!) Now you can peek behind the scenes of such wrangling as James Carville and his consultancy crew try to organize a presidential victory for Bolivian politician Gonzalo SÃ¡nchez de Lozada.
